P-Methylaminophenol Sulfate is found in permanent hair dyes.
Is chemically synthesized using a multi-stage process involving heating a mixture of hydroquinone and methylamine. It is performed under strict laboratory conditions to ensure the safety of workers and prevention of contamination.
Two of the most dangerous chemicals found in generic hair dyes are resorcinol, and toluene-2,5-diamine sulphate (TDS; 2,3). Both of these rated a high 8 according to EWG’s Skin Deep cosmetics database, but it’s very important to note why. Resorcinol has been placed on the UN’s list of endocrine disruptors, and TDS is even potentially carcinogenic.
P-Methylaminophenol Sulfate is used in the process of developing black and white photographs.
